CHARLES P. ACKERMAN, OF ALBION, NEBRASKA.

GRADING-MACHINE.

Specification of Letters Patent.

Patented Apr. 4, 1911.

Application filed June 13, 1910. Serial No. 566,636.

To all whom it may concern:

Be it known that I, CHARLES P. ACKER- MAN, a citizen of the UnitedStates, residing at Albion, in the county of Boone and State ofNebraska, have invented certain new and useful Improvements in Grading-Machines, of which the following is a specification.

This invention relates to road grading machines, and one of theprincipal objects of the same is to provide simple and eflicient meansfor depositing dirt taken from a cut in a road at any required hollowpointvat a suitable distance from the grading machine.

Another object of the invention is to provide endless carriers forconveying dirt to any required point, said endless carriers beingoperated by the weight of the dirt deposited thereon.

Another object of the invention is to provide a grading machinecomprising inclined drive-ways for carrying the dirt up to the top ofthe machine where said dirt is deposited upon an endless carrier, and bythe weight of the dirt the carrier is operated to deposit the dirt atany required point within a certain radius of the machine.

Still another object of the invention is to provide means for connectinga series of endless carriers to lead off from the machine and to beactuated by the weight of the dirt thereon, said carriers beingadjustably connected to the machine so that any required inclination maybe given to the endless carriers, depending upon the distance at whichthe dirt is to be deposited.

Another object of the invention is to provide means for swinging theendless carriers so that the dirt may be deposited at one side or theother of the road, or upon one side or the other of the machine.

Another object of the invention is to provide a grading machine whichcan be readily taken apart and folded into a comparatively small compassfor loading upon a wagon or wagons to be conveyed to the place that thegrading work is to be done.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawing, in which,

Figure 1 is a top plan view of a grading machine made in accordance withmy invention and shown set up in position for use. Fig. 2 is an endelevation of the machine. Fig. 3 is also an end elevation looking towardthe opposite end of the machine from that shown in Fig. 2. Fig. 4 is alon 'tudinal sectional view of the machine. is a side elevation of themachine.

Referring to the drawing the numerals 1 designate the uprights of theframe of the machine and connected together by means of cross bars 2 attheir upper ends. Inclined supports 3 are connected to the uprights 1 bymeans of stay bars 4. Metal braces 5 are connected to the uprights l andcross bars 2. Inclined drive-ways made up of suitable planks 6 areplaced upon the supports 3 and extend up and over the top of the frameto permit the teams to carry the dirt up and to deposit it in theopening or hopper 7 immediately over the endless carrier. A suitablerailing 8 is supported upon the top of the machine at opposite sides ofthe hopper 7., Inclined supporting members 9 pointed at their lowerends, as at 10, and adapted to be driven into the ground with theirupper ends converging, as shown more particularly in Fig. 2, areprovided with guy cables 11, which extend from stakes 12 driven into theground to the upper ends of the supporting members 9. These supportingmembers are provided with a series of perforations 13 for permitting theadjustment of a cross bar 14;, said cross bar being held in adjustedposition by means of suitable pins 15 which engage holes 16 in the crossbars 14 and the holes 13 in the members 9. Supported upon the cross bar1% is a roller 17 mounted in a stirrup 18. Metal supports 19 areconnected at their upper ends to the stirrup 1-8 and the lower ends ofsaid supports 19 are engaged in eyes 20 secured to the side 21 of theendless carrier. By means of this adjustment the endless carrier may beraised or lowered to give the required inclination for carrying off thedirt.

Braces 22 are connected at their upper ends to the members by means ofsuitable pins 23, while the lower ends of said braces are pointed andadapted to be driven into the ground. At a distance from the machinesimilar supporting members 9 are provided with the adjusted cross bar 14of substantially identical construction with those already described,and similar supporting rods 19 are provided for supporting the outer endof the endless carrier, as shown more particularly in Figs. 4: and 5.Inclined members 24 are provided for the outer members 9. p

The endless carrier comprises a series of slats 25 connected together asuitable distance apart by means of flexible bands 26 and covering theslats 25 is an endless apron 27 of canvas or other suitable materialadapted to cover the slats 25 and thus prevent the dirt from passingthrough between, said slats. Rollers 29 and 29 are journaled at the endsof the side members 21 of the carrier and a series of rollers 30 ofvarying sizes are journaled in the side members at suitable distancesapart to support the upper stretch of the carrier. Suitable rollers 31'are journaled; to brackets 32 secured to the sides 21 for supporting thelower stretch or sag of the carrier. Two or more of the side members 21may be connected together bymeans of suitable hinges 33 which aredetachably pivoted by means of'pins 34 so asto permit the folding. ofthe carrier frame for conveying the same from place to place upon awagon or other vehicle. The inner end of the carrier is supported upon aframe 35 provided" with a cross bar 36 having friction,

rollers or wheels journaled thereto, as shown more particularly in Fig.8. The bar 36 upon which the frame 35 is supported is pivot-ally mountedby means'of a pin 38 upon a sill 39 having a curved, bearing plate 40secured to the upper surface thereof. Stay members 41 are secured to thebar 39' and connected by means ofstakes 42 driven into the groundatthesides of the machine. By means of the pin- 38 the frame 35 may beswung from side to side to directthe endless carrier to one side or theother of the machine, so that the outer end43 of the carrier may bedisposed out ofalinement upon either side of the machine for depositingthe dirt at the required place.

Any suitable number of" carriers may be connected together for conveyingthe dirt any suitable distance and. the required in clinationmay begiven to the carrier by the adjusting devices previously described.

From the foregoing it will be obvious that the machine may be set up atany required point to receive the dirt through the opening 7 to bedeposited upon the endless carrier and conveyed to the required pointfor discharging the same, the endless carrier being operatedautomatically by the weight of the dirt deposited on said carrier. Itwill also be obvious that the carrier may be swung laterally to depositthe dirt at any required place. The machine can be quickly set up andcan be readily taken apart and placed upon a wagon or vehicle to becarried to the; place where it is desired to do the grading.

My invention is of comparatively simple construction, can bemanufactured at comparatively low cost and is exceedingly efficient forits purpose.

I claim:

1. In a grading machine, a frame, driveways leading to the top of saidframe and vices by adjusting pins, a roller mounted to move on the crossbar, a stirrupin which the roller is mounted, supporting membersconnected to the stirrup an endless carrier to which said supportingdevices are connected, and means for swinging the carrier.

3-. In a grading machine, a frame, inclined drive-ways leading to thetop of said frame and provided with a. discharge opening, an

inclined endless carrier mounted in the frame, a cross bar-verticallyadjustable upon the frame, a stirrup provided With rollers supportedupon said crossbar, supports connected to said stirrup at one end and atthe opposite end to saidendless carrier for adjusting the inclination ofsaid: carrier.

4 In a machine-ofthe cliaracter described; a frame, drive-ways leadingto thetop ofthe frame and provided with a discharge opening, an endlesscarrier mounted-on rollersand' disposed underneath the opening in saiddriveways, means for. adjusting the-inclination. of the carrier at theouter end thereof, and means for adjusting-thecarrier laterally at itsdischarge'end to deposit the dirt at different points outv of-alinementwith the center of the machine.

In testimony whereofIa-fiixmy signature in presence of two witnesses.
